The sensitivity is calculated to maximize the forecast error in the gray rectangle region. The rightmost panel measures the nonlinearity strength from the difference of two numerical simulations with opposite perturbation signs. These figures indicate the sensitivity analysis successfully capture the forecast error pattern similar to the actual errors in numerical simulations, though underestimating its magnitude.
